To all whom it may concern v Be it known that I, JEREMIAH CAMPBELL, a

citizen of the United States, residing at Newton, in'the county of Middlesex and. State of "Massachusetts, have invented a new and useful Improvement in Apparatus for Handling Coal or other Material, of which the follow- 7 prises the combination of primarymeans for lifting and transferring coal or other material like a. grab or shovel with secondary means for receiving the load of the. grab or shovel directly from it and for transferring it laterally and at any desired height to a pointer station of ations. 4 To indicate one of the uses of the invention, I have illustrated my improved apparatuses mountednpon a lighter or barge adapted to receive and transport coal in bulk and also, support and transport the handling machineryviz.', the grab or shovel for lifting the coal from the hold of the barge or lighter, for transferring it crosswise the barge, and the means for receiving the load of coal from the grab or shovel and transferring it lengthwise the barge or lighter. Sueha barge or lighter is especiallyadapted for'the coalingf of large steamers, as it provides means whereby the coal may not only be transported in bulk to the steamer, but may also without thereafter moving the barge or lighter with respect to the steamer deliver the-coalinto 'a number discharge and as'consecutive operof bunker-openings of the steamer in regular order or in any other order desired, so that the'filling of a nuinb'erof bunkers may be proceeding practically at the same time.

The capacity ofthehandling devices to deliver coal is much larger than the power of single bunkers to receive it, the size of the bunker-openings and the construction of the bunkersbeing such as to require. a limited,

delivery and much trimming of the coal by the bunker gang'as it isloaded into them. ,Therefore by a cross-transfer several bunkers may be supplied witheoal gat substantially.

This is for the purpose'ab'ove indicated of providing sufficient room for the secondarycoal-handling devices at one side of. the barge or lighter; The truck A is repre- 5 sen't'edaselevatedsuffieientlyabovethehatchway-coamingsto permit the crowning ofthe coal in .the hatchways and the operation of the shovel or grab when so crowned.v

The tower A carries a horizontal boom A upon which is mount'eda movable trolley A for transferring the rope orv ropes of the grab A lengthwise the boom or any part of it and while said grab and its rope or ropes are also being moved vertically with respect to the trolley.

i The tower, boom, trolley, and grab, with exceptions hereinafter noted, are like the same parts described in my application for Letters Patentof the United States, filedNovember 16, 1900, Serial No. 36,692'- th'at is, the boom is so supported and constructed, the tower is so arranged, and the trolley and grab so operated that the grab may take its load from a supply located anywhere beneath the boom zsbetween its ends and transfer it by a simultaneous vertical movement of the grab and horizontal movement of the trolley and for the full length of the boom or for any part of the boom and whether within the tower or at eitherside of it, the height at which the boom isr-supported by the tower and the free.-

)m from obstructions beneath it permitting these combined movements to take place within the limits. of the tower as freely as upon either side of it and the opening in the truck permitting the grab to take from a supply immediately below the tower-as well as from either side of it. It will not be, necessary for ine to describe in detail the construction of these parts.

I have represented a tower constructed of metal instead ofwood and a metal boom. The metal boom is made in three parts or sections, as described in said applicationviz., the central tower or section A and the outer or overboard sections A and A, which sections are movable with respect to the central section A to a vertical or. other positionv and independently of each other, and I prefer that one of the sections be longer than the other. The boom not only differs in construction from that "of the application referred to, but it also performs an additional function-viz., it is provided with a second set of tracks upon which a hopper is adapted to be supported and moved lengthwise the boom. The structure further varies with respect to the leading of the topping lift used in raising the boom-section and also with respect to the leading of the shovel-ropes and guiding and arrangement of sheave-rolls at the top of the tower, and these variations in the construction will be described hereinafter. The operation of thispart of'themechanism, so far as taking coal. and transferring it, is fike that of the devices of the said applicanon.

\Vith the present invention the coal is adapted to be delivered by the'grab to an auxiliary or secondary carrying or handling device, which'has a movement lengthwise the lighter or barge beloy the boom and transversely to it, and which secoh dary carrying device is adapted-to be vertically adjustable with respect to the lighter and the boom and is arranged to deliver coal through bunkeropenings in the side of a vessel and in any order desired. I Y

The secondary carrying device comprises a hopper B upon a truck B, which is supported by tracks mounted upon a horizontal girder or beam B The girder or beamis arranged lengthwise the barge or lighter upon the side less restricted by the tower and it is mounted upon standards or posts B B, rising from the deck of the barge or lighter, and

upon which posts'orstandards itis vertically movable to vary the height of the truck and hopper to any desired extent. This I have shown accomplished by means of suspendingropes b b, attached to the ends of the girder or support and extending over sheaves b at the tops of the standards-or posts and sheaves b at or near the bottoms of said standards or posts, from which .they preferably run to a winding-drum upon an engine on the lighter. The rails upon the girder are lettered Z1 and line, the inner one being higher than the outer one. This is for-the purpose of providing the hopper-truck and hopper with a more stable support on a narrow base.

The hopper B preferably ismade detach- "able from the truck B and of the shape represented in Figsj 1 and 3 and preferably so as to deliver its contents outwardfrom its lower end. It has the relativelylong outward-inclined bottom I), inclined sides'lfl, and a very nearly straight outer wall. It is open at the top and of any required size. The outer wall has near its lower end'an outlet 00, which is adapted to be closed and opened by the door 00;. (See Fig. 8.) The truck B,which supports it, is movable length.- wise the girder by any desired means. I have represented it as accomplished by means of They are shown in the drawings out of a draft wire or rope b which extends longi- I tudinally the girder in both directions about sheaves 5 19 I The wire or rope'passes from the girder to a winding-spool of the engine. The truck-drawing rope or wire thus led will adapt itself to any height of the girder and Without requiringany take-up, it being understood that the girder is lifted or lowered from time to time, as may be required to bring the discharge-outlet of the hopper into line with the line ofbunker-openings. It should also be borne in mind that the truck and hopper are movable at any height of the girder lengthwise it and any distance upon it in either direction from the boom for the -purpose of transferring the coal which it received from the rah to any one of a number of bunker" openings or chutes, the means for operating the hoppedtruck being under the control of the engineer of the-engine and of a nature tomove andstop the truck at his will. This-renders it possible to deliver from the barge or coal in bulk first a load atone bunker-opening, a second load at another bunker-opening, a third load at still another opening, and so on, So that with'a single supplying-grabfand the supplemental transfer.- ring devices it becomes possible to work the grab to its fullest capacity,which is far greaterthan thatrequired tosupply a singlebunker, and-thusffeed at the sametimea relatively large number of bunkerswvith-coal as fast as they can take care of it, it being understood that each bunker has a gang of-lnen whose duty it is to trim the'coal in'the bunkers as it. is supplied them; L have spoken of truck and in con nection' with the boom and the grab; and so-that it may be moved horizontally "upon the boom to" any desired position -bemath any part of it and may there receive coal fromthe grab which-has been moved to discharge its lead into it. It. should be stated that coal-handling apparatus especially designed'to load large steamships shouldv have as much flexibility and, adaptability as possi ble in order to meet the greatly varying conditions which exist indiiferent steamships, no

two ships having exactly/the same arrange mentof bunkers eitheras to height, distance apart, or location. ,Many of the bunker-openings are in the sides-of ships, but some are overhead, and it is therefore desirable that the apparatus should have provision for overhead as well as side work. The portable hopper is useful for overhead work; It isrepresentd as suspended from a truck C, 1nount-' 'ed on the tracks 0 c of the boom. 'lhis'truck -C-is'in twoparts, one ofwhich, the part 0 3 is mounted upon the track 0, and the other,

the part 0 is mounted upon the-track 0. Each part consists of a roll. from which extends downward an arm c. The truck parts are kept'from tipping or. leaving the tracks by the angle-iron g'uards 0 There is secured in lieu thereof to the lower ends of they arms a wire rope 0 which extends to a bridle c attachable at each end to the upper corere of the hopper, (see Fig. 2,) preferably by meansof hooks or in any other desired way. i Thehopper-truck is constructed so that the hopper may be removed from it by an upward vertical movement, and when it is desired to use the hopper independently of the truck itis connected with the truck 0 by means of the suspending-ropes e and the boom-truck then moved upon. the boom to the required position. The hopper may thus be taken front its truck, attached to the boom, and trans;

ferred upon it to any position convenient for overhead or other discharge. The grab is position the hopper may bein."

the hopper as removable from the track. This is 'for the purpose of pe'rmittingit to be used independently offthe then operated to'deliver its load'towhat'ev'e'n Each hoom-toppinglift'D is "constructed and led soas to take .hold of a boom-section at or near its outer end by a bridle attachthe tower, which is connected by. a tackle d ,mentfif desired, and is led to a block d'on with'a block (1 on the tower-truck and so that g the tackle shall be atone side'of'the boom.

The necessity for this adjustmentof the girder is apparent when it is remembered that the barge or lighter itself may be higher at one end than at the other, and that the same is also true of the vessel, and that these relative inclinations are liable to considerable variance as the loading proceeds.

I prefer to make he central or fixed section A of the boom of a length to extend from the ondary handling apparatus and to there conn-ect the movable end-A to it. This provides tion A is connected to the central section at extends, and in which the central fixed section extends from the other side of the tower,

to the outward extension of the fixed section at some distance from that side of the tower. This provides for a permanent or fixed relation between the fixed section A of the boom that for loading into outboard bunker-openings a movable section of the boom is not employed.

I prefer that the lighter or barge be made of steel and that it have compartments h, adapted to receive water ballast and by means of which it may be sufficiently immersed in the water to furnish'a stable support for the tower when it is without other load.

I have already described somewhat in detail but notconnectedly the operation of the apparatus. I will now state that the operation of the entire apparatus is under the control of a single engineer or operator stationed in an operators house over the engine-room and at or near one end of the barge or lighter.

The engine is of any ordinary or suitable construction having appropriate wire or rope winding drums or spools and suitable levers and clutches for independently actuating and holding them and said levers, andalso the lewithin the command of the operator.- He

Not only may a single operator thus govern and direct the loading of the grab, the extent and direction of. its movement to the hopper, its discharge into the hopper, and

the subsequent lateral feed and delivery of the load by the auxiliary feeding mechanism,

So I

but he also has within his control; the means.

for moving the tower-lengthwise the barge or;

Of course the auxiliary devices may notlalways be employed. The suspended hopper is used when desired. The apparatus is adapted for all the uses set forth in the said application and without employing the hopper in either of the two ways described. The coal may be taken from the hold of the lighter or barge carrying the tower and both'handling 4 devices, or fromv another lighter'or barge, or from a stationary pile.

The invention would be practiced if the devices werev mounted upon stationary supports instead of upon the lighter or barge and whether'the'tower is made movable the girder for the purposes of its adjustment or not.

w I have spoken generally of grabs as a means for lifting the coal andtransferring it, and I have referred tocoal as the material to be shifted by it. I do not use these terms, how- 'EIG ever, in a limiting sense,-as by grab I mean is anyof the usual devices for lifting and trans ferring material, and by coal any materia.

which is capable of being lifted and transferred by such a lifting device.

The grab which I have shown is of the kind which is automatically or self loading and e which also automatically delivers its lead, and While I do not confine the invention to this form of grab, yet I prefer it for inanypurposes, and especially in handling coal, as by this means the transfer of the coal from-the hold of thebarge or lighter or frombulh is entirely automatic to the station or pointof final discharge into the bunker or ch ate. 1 also prefor to use the type of transferring-trolley.described in conjunction with the said graband means for-operatingit specified, .in,that it is readily adjusted to the conditions of thewoipk, I

I-meanby that that the height to which the grab is lifted is in its transfer from bulk to the auxiliary carrying device governed or controlled by the height of the said au-xiliary device, and as this has quite a range the advantage of this construction in preventing unnecessary extent of movement is apparent.

. I would further say that the height at which the auxiliary carrying device discharges is fixed by the height of the openings .to the crosswise the bargeor lighter to an auxiliary cross-transferring device, said means comprlsing a tower, a horizontal boom carried by the tower, a trolley movable upon the boom and a grab or other conveyor movable toward and from the trolley, the said auxiliary crosstransferring device comprising a beam or girder carried by said barge or lighter to extend lengthwise it and crosswise and beneath the boom, a truck, movable upon said beam or girder and a hopper or receptacle carried by said lZIll'CkpfldlPllGd to receive the contents of the liftinggrab or conveyer and to trans-' fer them lengthwise said barge or lighter to a discharging'position.
